A Delaware man was arrested after police say he threatened to bring an AK-47 to his work place.

Police say Brandon Miller, 30, an employee at the Discover Bank on the unit block of Reads Way in New Castle, was placed on administrative leave on Wednesday. This was due to an unreported incident in which Miller allegedly threatened an employee after being reprimanded at work the day before. Police say Miller was told he was not allowed to return to work or enter the property until he was contacted by Discover Bank. During a later conversation with another person, Miller allegedly mentioned that he would bring an AK-47 to work and shoot the place up, according to investigators.

On Thursday, around 10 a.m., security personnel spotted Miller enter Discover Bank in his vehicle, according to investigators. Security immediately placed the building on lock-down and called police. A police officer and his K-9 partner arrived at the bank shortly after and observed Miller sitting on a table in a small picnic area near the front doors of the building, according to investigators. The officer ordered Miller to the ground and took him into custody without incident. A canine team that specializes in bomb detection later conducted a sweep of Miller’s vehicle. During the search, investigators say they found a BB gun in the trunk which was confiscated. They also say they later found 4.4 grams of marijuana inside his home.

Miller was charged with a felony count of terroristic threatening, criminal trespass, possession of marijuana and other related offenses. He was arraigned, released on $4,500 unsecured bond and ordered to have no contact with Discover Card Bank.
